Point-Slope Form of a Line

Question 1

Which point-slope equation represents a line that passes through (3, –2) with a slope of negative StartFraction 4 Over 5 EndFraction ?

Revolt · Accepted Answer

y + 2 = –(x – 3)

Question 2

m = –2m = –(1/2)✔ m = 1/2m = 2

Revolt · Accepted Answer

✔ m = 1/2; The slope of the line is .: m = 1/2; A point on the line is .: (1, 4)

Question 3

(–4, –1)(4, 1/2)(1/2, –1)✔ (1, 4)

Revolt · Accepted Answer

✔ (1, 4)

Question 4

y – 1 = 3(x + 0)y – 0 = 3(x – 1)✔ y + 1 = (1/3)(x + 2)y + 2 = (1/3)(x + 1)

Revolt · Accepted Answer

✔ y + 1 = (1/3)(x + 2)

Question 5

f(x) = (1/3)x – (5/3)✔ f(x) = (1/3)x – (1/3)f(x) = 3x – 3f(x) = 3x + 1

Revolt · Accepted Answer

✔ f(x) = (1/3)x – (1/3)

Question 6

A tile factory earns money by charging a flat fee for delivery and a sales price of $0.25 per tile. One customer paid a total of $3,000 for 10,000 tiles. The equation y – 3,000 = 0.25(x – 10,000) models the revenue of the tile factory, where x is the number of tiles and y is the total cost to the customer.
